Verifact D and D-V Microphones connect directly to any Louroe Audio Base Station or to a Louroe Audio Interface
(Model IF-1, IF-2, IF-4 and IF-8). A small terminal block is located on the microphone pre-amp, and marked A, B,
C.
Using recommended cable, connect as follows:

®

Red wire connects to terminal A (+12Vdc)
Black wire connects to terminal B (audio output)
Bare wire connects to terminal C (ground)

If using cable from other manufacturers, color code may vary.

INSTALLATION AND OPERATING INSTRUCTIONS

CONNECTING VERIFACT D OR D-V MICROPHONES TO OTHER AUDIO RECEIVING

®

DEVICES

If a Louroe audio base station is not used and microphone is to be connected directly to another
audio receiver, use the following procedure:

1. Apply 12 Vdc power (100mA minimum) to PC board’s terminals A and C. A is positive, C is ground.

2. Using a single conductor shielded cable, 22 gauge with a 24 gauge drain wire, connect shielded wire to
terminal B and drain wire to terminal C (C is common).

3. Run other end of cable to the audio receiver. If audio input is an RCA connection, solder on an RCA
connector with wire from terminal B of microphone going to the tip of the RCA plug, and wire from terminal
C going to the sleeve of the plug. Connect RCA plug into “audio in” of the audio source. If connection to
the audio source is a terminal block or strip, refer to audio receiver’s instructions for proper connection.

See wiring configuration below for different audio plugs (black wire is used instead of bare wire for ground)
